2. Backbone Update Ring 4 IRUs signed –Capital Review completed 8/06/07 –Gear is being processed 10 Gbps upgrade to parts of Rings 1, 2 and 0.

3. Backbone Update Looking two options for fall –Using I2 commodity peering service; so far have seen ~600Mbps –Will increase capacity with upgrades and when M120 goes in –M120s POs have been cut –Looking at Level3 using a 10 GigE pipe. Can buy as a burstable service, I.e. would really add a lot of “insurance” in uncertain times

4. Backbone Update Time Warner Telecom - 625 Mbps Considering changing commodity service from 4 OC-12, and 2 GigE to two 10 Gbps connections from different providers

10. Joint Venture with State Three basic designs on table –Separate Lambda etc - not likely –Completely shared infrastructure - not likely –Shared 10 Gbps Lambda, separate but interconnected routers They need enterprise services We need core services Pragmatic issue - They have two class B’s in their network and own AS MPLS with peering?
